[LON-CAPA-users] generate same exams in two different sections??

[Stuart Raeburn]

Hi Doug,

LON-CAPA uses a message digest of the unique resource identifier (the  
"symb"), the internal LON-CAPA courseID, and the exam CODE to create  
the random seed.

So if 104D section and the 104O section are different LON-CAPA courses  
(with different courseIDs), which the LON-CAPA Course Catalog for the  
uiuc domain for CHEM for Fall 2014 indicates is the case, then exams  
generated in the two courses would be expected to use different seeds  
for the same CODE.

For future semesters you might consider aggregating the 104D and 104O  
students in a single LON-CAPA course, but affiliating the student with  
different groups (one for D, one for O), and then setting parameters  
(e.g., content access etc.) based on group affiliation etc.

For now, you could create yet another course (with enrollment from  
both 104D and 104O courses) and generate the exam there for students  
from both the D and O sections.  That would mean students would need  
to log-in to the "exam" course to see their submission history etc.   
Alternatively, you could set student access dates in the exam course,  
such that student roles would have already expired, print and grade  
the exam in the "Exam" course and then export the grades, followed by  
uploading grades into a score upload form in the separate 104D and  
104O courses.  However, that approach would provide students with only  
the points earned in the exam, and no view of their submission  
history/correct answers for their randomization etc. for individual  
exam questions.
